Installing New Steam Radiator
I'm renovating two bedrooms in my house and am installing two new steam radiators as part of the renovation. The radiators are freestanding, cast iron radiators made by Governale. The system is single-pipe.
The radiators have 1 1/4" NPT openings at the bottom (for the valve at one end and plug at the other) and 1" NPT openings at the top. Additionally, about 1/3 of the way up each end section, as well as next to the top 1" NPT opening, there are two small bungs.
Looking at the other radiators in my house, the vents (which are 1/8" NPT) are all installed in the bung that is 1/3 of the way up the end section.
My plumbing supply company said that the vents should be installed using a 1" NPT - 1/8" NPT reducer at the top of the radiator so that the whole thing gets hot. However, I've never had an issue with my other radiators getting completely hot, and don't like the way the vents will look if installed at the top (I'm installing Macon single-pipe thermostatic radiator vents).
1. Should the vents be installed at the top, or is it OK to install them using the bung 1/3 of the way up the end section?
2. Are those bungs meant to be drilled/tapped, and if so, is it standard practice to do that in the field (vs. ordering them pre-tapped)?
Appreciate the help.
